+Getting Started

+
+Here is a quick example of how to fit an xml thermodynamic model to experimental data.
+
+This code fits Nd standard enthalpy in the "twophase.xml" cantera file to the 
+experimental data in "Nd_exp_data.csv".
+
+This code requires that you copy and paste the "elementz.xml" file in the llepe's data folder into 
+the Cantera's data folder located in your environments site-packages folder.
+
+The code then produces a parity plot of the measured and predicted concentrations of Nd 3+ in the 
+aqueous phase.
+
+.. code-block:: python
+
+	from llepe import LLEPE
+	opt_dict = {'Nd(H(A)2)3(org)_h0': {'upper_element_name': 'species',
+                              'upper_attrib_name': 'name',
+                              'upper_attrib_value': 'Nd(H(A)2)3(org)',
+                              'lower_element_name': 'h0',

+                              'input_value': -4.7e6}}
+

+Welcome to llepe's docs! - the Liquid-Liquid Extraction Parameter Estimator
+===========================================================================
+LLEPE is a package for thermodynamic parameter estimation for liquid-liquid extraction modeling
+
+LLEPE takes experimental data in a csv and system data in a xml.
+
+The package then uses Cantera, another python package, to simulate equilibrium.
+
+Error between predicted and experimental data is then minimized.
